Answer:
16/25
Step-by-step explanation:
We just have to find the probability that the 8 non-defects are chosen.
1. Chance first defect is undetected: 8/10 = <em>4/5</em>
2. Chance second defect is undetected: <em>4/5</em>
3. Total probability': 4/5 * 4/5 = 16/25
Answer:
Michaela gets 3.45$ back.
Step-by-step explanation:
1 carton of eggs = 1.58$
she buys 2, so 2 times 1.58= 3.16$
1 pound of turkey = 6.99$
she buys 4.15 pounds, so 4.15 times 6.99= 29.01$
she buys a jar of jam for 4.38$
4.38 + 3.16 + 29.01 = 36.55$
4 times 10= 40
40 - 36.55 = 3.45$
Answer:
Original claim is 
Opposite claim is 
Null and alternative hypotheses:


Significance level: 0.01
Test statistic:
We can use TI-84 calculator to find the test statistic and P-value. The steps are as follows:
Press STAT and the scroll right to TESTS
Scroll down to 2-SampTTest... and scroll to stats.
Enter below information.







Pooled: Yes
Calculate.
The output is in the attachment.
Therefore, the test statistic is:

P-value: 0.4412
Reject or fail to reject: Fail to reject
Final Conclusion: Since the p-value is greater than the significance level, we, therefore, fail to reject the null hypothesis and conclude that the there is sufficient evidence to support the claim that the samples are from populations with the same mean.
Answer:
The product represent the number 
Step-by-step explanation:
To find : The decimal 0.3 represents What type of number best describes 0.9, which is 3.0.3?
Solution :
0.3 represents 
0.9 represents 
If we multiply 0.3 by 3 we get 0.9
As, 


Therefore, The product represent the number 
Seven-thirty.
A half an hour past seven o'clock.
